More than 50m

More than 50m Coherence Length Overview

Coherence length is defined as the distance over which the laser beam can travel without experiencing a phase discontinuity.  This is a critical parameter in applications such as holography and interferometry where beams may be required be split with each leg going a long distance before being recombined.   The coherence length is directly related to the linewidth of the laser, and as a result, long coherence length lasers are almost exclusively single mode.   Here at RPMC Lasers, we offer a wide range of diode-pumped solid-state (DPSS) lasers with a coherence length of more than 50m.

LaserBoxx SLM Series

Laserboxx SLM Series by Oxxius

The LaserBoxx-SLM Series is a single longitudinal mode (SLM) CW diode laser module available in wavelengths at 633nm, 785nm, and 830nm delivering ultra-narrow linewidths thanks to its excellent temperature stability and low noise current. The Oxxius proprietary, embedded firmware locks the laser on the same mode at each startup. This compact, self-contained laser module is available in turn-key or OEM versions and utilizes a proprietary alignment-free, monolithic resonator, and comes standard with a graphic user interface with remote diagnostics via USB, RS232, or direct I/O interface.

LRL Series

LRL Laser Series by BKtel

The LRL series is a 1550nm, high-power, continuous-wave (CW) fiber laser, providing up to 1W of output power from a single-mode fiber. This series offers power tunability ranging from 10%-100%, is available with standard or polarization-maintaining fiber with FC/APC fiber or an optional collimating lens, produces a perfect TEM00 beam, and offers high-speed triggering and modulation.
